Oxford University Press published a journal article by Assistant Professor of Science (Evolutionary Photonics and Ornithology) Vinod Kumar Saranathan titled the Evolution of Insect Iridescence: Origins of Three-Dimensional Photonic Crystals in Weevils. In this research, Asst Prof Saranathan and his co-researchers trace the evolution of such vivid colours produced by 3D photonic crystals within elytral (wing casing) scales across all weevils.
